My tumour was relatively small at 10mm and was also close to the cochlear.
Swelling does not mean hearing loss.. The reason the tumour swells is that as the cells begin to die they lose their ability to control the amount of water within the cell.
Eventually the cell wall ruptures, the cell dies.
So think of your tumour now as a dry hard sponge, and a radiated swollen tumour as a wet sponge.

Tinnitus is also gone.
I did decide to get my tumour treated proactively, accepting that it may lead to a potentially worse outcome.
Everyday after Cyberknife, when my symptoms got worse, at least I knew I was on the road to recovery. I really disliked the uncertainty of waking up every day in W&W and noticing the hearing was a bit worse, the tinnitus was a bit louder and my head seemed to have more cotton wool in it.
